Can an insurance company drop you if you get sick?

Question Details:

My sister was very sick and was hospitalized for about a month; she is still having complications. She was released from the hospital 2 months ago. She is on her husband's insurance through work. He's been employed at this small road construction company for over 20 years. They were notified today their insurance is canceled but no one else's was cancelled. Is this legal?
